Heat map of seven male-borne volatiles (columns) identified by GC×GC/MS analyses in seven populations (rows) of the Anastrepha fraterculus cryptic species complex. The dendrograms were created using correlation-based distances and the Ward method of hierarchical clustering (P < 0.05). Key: AL – Alagoas, AL, Brazil; BEN – Bento Gonçalves, RS, Brazil; DUI – Duitama, Colombia; IBA – Ibague, Colombia; PEL – Pelotas, RS, Brazil; SAO – São Joaquim, SC, Brazil; SIB – Sibundoy, Colombia. Epianas – Epianastrephin; Z.E.Far – (Z, E)-α-farnesene; E.E.Far – (E, E)-α-farnesene; Z.Nonenol – (Z)-3-nonen-1-ol; E.Z.Nona – (E, Z)-3,6-nonadien-1-ol; a.Pinene – α-pinene.
